Hi,
Welcome to ehealthforum,
The white rash that you describe along with the vaginal itching could suggest possibility of infection. Do not ignore your symptoms. Consider visiting your doctor/gynecologist at the earliest for thorough examination and further evaluation (vaginal swab/smear test, skin scraping test) to look for the underlying cause. Treatment as needed (based on examination findings and investigations results) would be started to help you control the symptoms. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Drink plenty of water. Take adequate rest. Maintain healthy diet and lifestyle. Avoid vaginal douching, or use of harsh soap or perfumes in the area. Use loose cotton undergarments and avoid use of tight fitting clothes. If infective cause is detected, and if you are sexually active, get your partner also treated simultaneously to prevent chances of re-infection, and avoid having intercourse while being on treatment.
Take care.
